Walmart announced Tuesday it will end the sale of handgun ammunition, a decision that comes as the retail giant faced pressure to curb gun and ammunition sales in the wake of a shooting at its store in El Paso, Texas.

In an open letter to Walmart associates, CEO Doug McMillon said that the store plans to discontinue sales of short-barrel rifle ammunition and no longer sell handgun ammunition. The Bentonville, Arkansas-based retailer will also no longer sell handguns at its stores in Alaska, marking a complete exit from the handgun market.
